This document will supersede EN 13813:2002.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports basic work requirements for construction works of
Regulation (EU) No 305/2011 on construction products.
For relationship with the Regulation, see informative Annex ZA, which is an integral part of this
document.
The significant technical changes between this European Standard and the previous edition are listed

Introduction
The properties required of a screed are related to its use.
They are considered in two groups: those relating to the fresh, unhardened screed material and those
relating to the hardened screed material.
The properties achieved depend essentially on the type or types of binder used and their respective
proportions. The type of aggregates, admixtures and/or additions used can achieve special properties.

1 Scope
This European Standard specifies requirements for the following types of screed material as defined in
EN 13318:
— Cementitious;
— Calcium sulphate;
— Magnesite;
— Mastic asphalt;
— Synthetic resin.
All types of screed material may be used for internal applications.
Cementitious screed material may be used for both internal and external applications.
This European Standard specifies the performance for fresh and hardened screed materials.
The floor screed materials could be monolayer or multilayer.
This European Standard specifies the assessment and verification of the constancy of performance and
the classification and designation of screed materials.
This European Standard does not provide criteria or recommendations for the design and installation of
screed materials.

The requirements and properties specified in this standard shall be defined in terms of the test methods
and procedures referred to in this standard. For these tests the screed material shall be sampled and
